The MAYDAY LONEWORKER safety system is designed to raise an alarm if a lone worker becomes incapacitated. Once the Mayday is armed, the primary countdown timer 20 - 60 minutes is started and indication is given by countdown LED's. At the end of the primary period the secondary timer 2 - 10 minutes starts and an audible and visual warning is given to prompt the lone worker to acknowledge there presence by pressing the OK button. As the timer approaches time out, the indications become more urgent. If the lone worker fails to respond the Mayday signals for assistance.
